TESTING-MACHINE.

Specification of Letters Patent.

Patented Apr. 19, 1910.

Application filed October 29, 1903. Serial No. 460,082.

To all whom it may concern:

Be it known that I, JOHN VAN IVIGHEREN RnYNDnRs, a citizen of the UnitedStates, residing at Steelton, county of Dauphin, State of Pennsylvania,United States of America, have invented certain new and usefulImprovements in Testing-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to machines for testing the relative resistance towear of materials, and has for its object to subject a plurality ofportions or sections of such material to like wearing conditions and isparticularly applicable to testing the wear of railway rails, saidrails, or portions of rails, being reciprocated while in contact withthe wearing element, this wearing element being preferably, but notnecessarily, a suitably mounted railway car wheel.

Referring to the drawings in which like parts are similarly designated,Figure 1, is a side elevation of a testing machine embodying myinvention. Fig. 2, a front elevation. Fig. 3, a plan of the machineshowing the car-wheel support in horizontal position, instead of ininclined position as in Figs. 1 and 2. Fig. 4 is a section on line 4-4of Fig. 3 of the forward adjustable portion of the two part arm.

The machine comprises a frame A on which is mounted a horizontal bed Breciprocating between lateral, vertical standards C. On the base orframe A is secured ,a shaft D on which is mounted a loose pulley Fsituated between adjacent fast pulleys E and G, and there is a belt anda crossed belt 9 to a drum H, mounted on a shaft I, which shaft is themain driving shaft of the machine, being driven by a pulley K. The poweris applied to pulley K by a suitable belt. A vertically adjustable crossrail L is mounted on the standards C above the bed.

The structure so far described is similar to well known machine toolshaving recip rocating beds, and that have suitable mechanism timed forreciprocating the bed, the

detailed structure of which is well known and forms no part of thisinvention. These features may be varied as desired, an essentialstructure for the purposes of this invention being a reciprocable bed.

On the shaft I is pulley 4, belted by a belt 5 to a pulley 6, the lattermounted on a shaft 7, supported in bearings 8, 9 and 10. The bearings 9and 10 are formed on a saddle 11, which is slidably mounted on the crossrail L to permit lateral adjustment, so that the bearings 9 and 10 aremoved simultaneously with the saddle when it is laterally adjusted. Onshaft 7 is secured a pulley 12 that rotates with said shaft. Free toswing with respect to the shaft 7 is a swinging arm 13 having ears orbearings 14 at one end through which shaft 7 passes. These bearings 14are adjacent and between those 9 and 10 on the saddle, or otherwise, andthe arm is provided on its top and intermediate its ends with lugs 15between which is pivotally secured the lower end of a link 16, whoseupper end is pivotally connected to a lever arm 17 carrying anadjustable weight 18, and pivoted in the ears of a bracket 19 projectingfrom the saddle 11. The swinging arm 13 carries at its free end asupport 13 for the wearing element, said arm and support being providedwith circular abutting plates 20 adjustably connected together in amanner to permit the support to be positioned at any angle with respectto the arm.

In one of the circular abutting plates 13 are secured bolts 113 thatproject through arcuate'slots 13*, Fig. 4, in the companion circularplate or end of the support 13 or vice versa, whereby said arm andsupport are secured together. The support 13 has two spaced bearings 21and 22, supporting a shaft 23 carrying a belt pulley 24, belted by abelt to the pulley 12 fast on shaft 7. On the shaft 23 is mounted awearing element, shown in the drawings as a car-wheel 24 and preferably,but not necessarily a thrust ball bearing 23 both the bearing 25 and thewheel 24 being between the bearings 21 and 22.

I have shown secured to the reciprocating bed B of the machine a chuck26 forming a continuous inclined support in which are secured aplurality of alined sections of rails R, R R etc. This chuck is hereshown of such form as to hold the sections of rail in inclined position.The inclination of the alined sections of rail is varied by supportingthem in other chucks having the desired inclination or in any othersuitable manner.

The operation of the testing machine is as follows: Rail sections R, R,R etc., two or more in number are placed in alinement so that theircontact surfaces with the wearing element or car-wheel 24- are in asubstantially straight line, and in the drawings I have shown these railsections mounted in a chuck 26 in an inclined position, so as to producea wear against the side of the head of the rail by the flange of thewheel as well as on the top of the rail by its tread. The manner andcharacter of mounting the rails are quite immaterial so long as they areheld in a relation to the reciprocating bed B, on which they aremounted, at that angle at which the test is desired to be made. In thepresent instance, the rail sections R are held inclined and the wheel 24is held in a similarly inclined position by adjusting the support 13with respect to the swinging arm 13 by means of bolts 113 held in one ofthe abutting plates and projecting through the arcuate slots 13 in theother plate. The desired weight or load on the wheel is obtained bymeans of the adjustable weight 18 on arm 17 acting through link 16 toload the swinging arm 13. Power is applied to pulley K by means of abelt or other suitable device which transmits movement through the shaft1, and belt or belts e or g to the fast pulleys E or G, there beingsuitable and well known mechanism for shifting the belts to and fromloose pulley F on shaft D that actuates the means to reciprocate the bedB of the machine.

Any suitable counting mechanism may be fitted to a reciprocable part ofthe machine in order to count the number of movements that the rails tobe tested are making or have made. The tops of the rails being inalinement, the wheel travels over all of them whether they be of thesame profile or not, and thus subjects all the rail sectionsmounted onthe bed to the same conditions of wear, and thereby determines therelative wearing qualities of the different grades of material of whichthe rail sections are made.

It is not necessary under all conditions that the wheel 21 be driven andin those cases one or both of the belts 5 and 25 may be removed. Inplace of the car-wheel 24: any other wearing element may be substituted.

I claim:

1. In' a testing machine, the combination with a reciprocable bed; of aswinging arm, means on said arm to support a rotatable wearing element,means by which said supporting means may be adjusted and held in itsadjusted position, supporting means for said arm to permit movementthereof with respect to the bed, and means to drive said element.

2. In a testing machine, the combination with a reciprocable bed; of aswinging arm, means on said arm to support a rotatable wearing element,means by which said supporting means may be adjusted and held in itsadjusted position, supporting means for said arm to permit movementthereof with respect to the bed, means to drive the wearing element andmeans to load the arm.

3. In a testing machine, the combination with a reciprocable bed; of asaddle adjustable transversely of the bed, an arm pivoted in said saddleto swing vertically, supporting means on said arm, a rotatable wearingelement mounted in the supporting means, means by which the angularityof the supporting means is adjusted and so held, means to drive thewearing element and means to load the arm.

a. In a testing machine, the combination with a reciprocable bed and across rail above the same; of a saddle adjustable along the railtransversely of the bed, a shaft supported from said rail and saddle, anarm pivoted on said shaft at the saddle, a support on said arm, means bywhich the support is adjusted with respect to the arm and held in itsadjusted position, a short shaft carried by the adjustable support, abelt pulley on each of said shafts, a belt connecting the pulleys, alever arm pivotally supported from the saddle connected to the arm and aweight adjustable along said lever arm.

5. In a testing machine, the combination with a reciprocable bed and across rail above the same, of a saddle adjustable along the railtransversely of the bed, a shaft rotatably mounted in journals formed onthe saddle, an arm pivot-ed on the shaft between said journals having acircular plate on its free end, a forked supporting member having acircular plate provided with arcuate slots for the reception of bolts onthe plate of the pivoted arm, a short shaft journaled in the fork ofsaid supporting member, a belt pulley on each of said shafts, a beltconnecting the pulleys, a wheel fixed on the short shaft, a bracketformed on the saddle, a lever pivoted in the bracket extending over thearm, a link connecting the lever and arm and a weight adjustably mountedon the lever.
